I have an old platform configuration, and the video chip is an Ati ES 1000 which ia re badged Rage Pro. Tried to install win 7 once and had no real drivers for it on amd website. Only for Win 9x, Win2K and WinXP32. Would it work to install the drivers in Compatibility mode under Win 7? I want to have access to changing the refresh rate and the resolution. And gamma setings among other parameters. My other options would be to get a more recent videocard with win 7 support, but I am really limited to PCIEX X1 or regular PCI. Cheapest option would be 8400GS
